Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (402 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Direct Equivalents (all parameters identical):

• CRCW0603402RFKEA (Vishay Dale)
• ERJ-3EKF4020V (Panasonic Electronic Components)
• RMCF0603FG402R (Stackpole Electronics Inc)
• RMCF0603FT402R (Stackpole Electronics Inc)

Similar Equivalent (all electrical parameters identical; differs in automotive qualification):

• RC0603FR-07402RL (YAGEO) — lacks AEC-Q200 automotive rating but maintains all other electrical and mechanical specifications

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 qualification, select from the direct equivalents: CRCW0603402RFKEA, ERJ-3EKF4020V, RMCF0603FG402R, or RMCF0603FT402R. All four maintain identical electrical performance and thermal characteristics while offering active product status and established supply availability.

ERJ-3EKF4020V (Panasonic) and RMCF0603FT402R (Stackpole, Tape & Reel packaging) present the highest inventory levels, supporting production continuity.

For non-automotive applications where AEC-Q200 certification is not required, RC0603FR-07402RL (YAGEO) provides electrical equivalence with moisture-resistant thick film composition and active status.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07402RL replace MCR03EZPFX4020 in automotive circuits? A: RC0603FR-07402RL lacks AEC-Q200 automotive qualification. Use only in non-automotive applications. For automotive designs, select CRCW0603402RFKEA, ERJ-3EKF4020V, RMCF0603FG402R, or RMCF0603FT402R.

Q: What is the difference between RMCF0603FG402R and RMCF0603FT402R? A: Both are Stackpole RMCF series 402 Ohm resistors with identical electrical specifications. RMCF0603FG402R is supplied in Cut Tape (CT) packaging; RMCF0603FT402R is supplied in Tape & Reel (TR) packaging. Select based on assembly process requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (CRCW0603402RFKEA, ERJ-3EKF4020V, RMCF0603FG402R, RMCF0603FT402R, and RC0603FR-07402RL) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Can I use these substitutes interchangeably on the same PCB? A: Yes, for electrical performance. All direct equivalents and the YAGEO part share identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Verify packaging format (Cut Tape vs. Tape & Reel) matches your assembly equipment.

Q: What is the temperature coefficient significance? A: All listed parts maintain ±100ppm/°C temperature coefficient across the -55°C ~ 155°C operating range, ensuring consistent resistance stability across automotive temperature extremes.
